200
In a parallel circuit, this is what is always the same for each branch.
What is the voltage drop?
200
The person who decided that the charge of the electron should be defined as negative, which in retrospect was really a bad idea because it messed up the definition of current. (That's probably why no one liked him and he was never elected president.)

What is the the total voltage of a series circuit where the potential difference of R1 is 10V, R2 is 5V and R3 is 1V?

What is 16V

400
The standard SI unit of energy.
What is Joule?
400
Parallel circuits often contain one of these, a device which closes the entire circuit in case the total amount of current becomes dangerously high.
What is a circuit breaker? (Or, what is a fuse?)
400
He designed the first AC motor, better light bulbs than Edison's, and a method to transmit electricity without the use of wires, but despite the film The Prestige, he didn't invent a cloning machine.
Who is Nikola Tesla?
