Question

A 10-ohm resistor has a constant current. If 1200 C of charge flow through it in 4 minutes what
is the value of the current?
A. 3.0 A
B 5.0 A
C. 11 A
D. 15 A
E. 20A

Answer 1

Answer:

B 5.0 A .

Explanation:

Hello.

In this case, since we know the charge (1200 C), time (4 min =240 s) and resistance (10Ω) which is actually not needed here, we compute the current as follows:

$I=\frac{Q}{t}$

Then, for the given data, we obtain:

$I=\frac{1200C}{4min}*\frac{1min}{60s}\\\\I=5A$

Therefore, answer is B 5.0 A .

Best regards!
