Question

When a 4 Ω resistor is connected across the terminals of a 2 V battery, the number of coulombs passing through the resistor per second is​

Answer 1

Answer:

0.5 ampere

Explanation:

V = I R

Current, I is the rate of flow of charge.

ie., I (in amperes) = Charge (in coloumbs)/time(in seconds)

I = V/R

= 2/4

= 0.5 A
