This knowledge, which sounds profound and complex, will become the focus of their research in the future.

Just thinking about it is enough to make them excited.

"Don't worry, sir, we will solve these problems as soon as possible. Based on what you said, how should we know the magnitude of the voltage or the magnitude of the current?"

Liu Zheng almost forgot that they were not scientists in the previous life who had explored and developed it bit by bit. They have not yet made an ammeter that can measure current.

Liu Zheng immediately wrote down the method of making an ammeter.

And tell them Ohm's law and electromagnetic law and let them study it on their own.

As for why Liu Zheng didn't explain it, it's because Liu Zheng didn't fully understand the complexity of these laws.

Let's leave things like this to these fanatical scientists.

Liu Zheng visited the electrical research laboratory, but he was thinking that hand-cranked generators had already been invented.

Should he let the light bulb appear in advance to facilitate the subsequent scientific research here?

Liu Zheng thought about it again and felt that it was still somewhat urgent, but he couldn't rush it.

Tungsten light bulbs are definitely not usable now.

Their current technology can still produce such light bulbs, so they can only consider lower-power alternatives.

Naturally, this matter was all left to those scientists.

Liu Zheng came to the research laboratory on engine development again, which will replace steam engines in the future.

It was also because of the invention of the engine that small but powerful battleships were able to flex their muscles on the battlefield.

It was also because of the emergence of the engine that cars replaced horse-drawn carriages and changed the way people travel.

It also changed the way of war, and the invention of the engine directly promoted the advent of tanks.

If we use the setting of the world of cultivating immortals to describe this era without nuclear weapons and powerful bombs, tanks are the land gods on the ground.

The armor of tanks and the firepower of artillery shells, the so-called cavalry, the so-called Cossack warriors, this cannon, that cannon.

Not enough to see at all.

Long Yan has mastered the steel materials that can be used to make tank armor.

It also has other technologies to build tanks.

But they have never successfully developed the core engine.

If the engine can be developed, it will not only be a tank, but also an airplane, mankind's hope for heaven, a product of the combination of aerodynamics and engine.

In today's era of aerodynamics, because of the emergence of Liu Zheng, people have begun to conduct extensive research on Liu Zheng's successful cases.

Liu Zheng once successfully built a glider and even used it to destroy a country's most important economic zone.

Liu Zheng also sent people to fly in the sky.

These are all manifestations of aerodynamic research results.

But now, engine research has reached a bottleneck.

The engine is an internal combustion engine. They don't know how to put coal in it to burn and then make the machine run.

They also tried a lot of combustion materials, and some were able to burn, but there was no way to provide reliable stability.

Sometimes, one combustion and one movement can completely destroy the engine.

Sometimes, even burning is not possible.

But these researchers have not found a way to solve these problems.

Liu Zheng came today to solve their fuel problem.

Liu Zheng brought another burning substance to the engine laboratory, which was a small can of oil found on an unnamed island.

Liu Zheng blended the oil with alcohol.

Put it inside the fuel tank.
