Question

A potential difference of 7.00 V is maintained across a 70.0-Ω resistor for a period of 80.0 s. What total charge passes by a point in one of the wires connected to the resistor in this time interval? 0.001 3 C

Answer 1

Answer:

Explanation:

the potential difference is 7v and resistance is 70 ohms the time period is 80.0s.

formular to calculate the amount of current flow is

I = V/R

v= volatge  across

R=resistance in the wire

substituting 7v for V and 70 ohms for R

I = 7/70 = 0.1A

0.1A is the amount of current flow.

Total charge for the time interval is

Q = I Δt

i is the amount of current

t is the time interval

Q = 0.1 * 80 = 8c
