Question

An electric current is produced by which of the following processes?
A. electrical resistance
B. transfer of protons
C. convection currents
D. Electromagnetic induction

Answer 1

Do you have any guesses?

Answer 2

C or D?

Answer 3

I agree! Have you ever learned about convection currents as applied to electronics?

Or do you know off-hand if electromagnetic induction produces a current?

Answer 4

I know nothing about this stuff! DO you know what one it is?

Answer 5

Be right back!

Answer 6

okay

Answer 7

Electromagnetic induction will create a potential difference by changing the magnetic field strength through a circuit.

Answer 8

so is it D?

Answer 9

Yup! I never learned about C. But, based on quick research, I don't think it's applicable. D will produce a current in a closed loop. It's how generators work!
