The compressor on an air conditioner draws 121 A when it starts up. The start-up time is about 0.505 s. How much charge passes a cross-sectional area of the circuit in this time?

61.105 C

Explanation:

Charge: This can be defined as the product of current flowing through a circuit and time. The S.I unit of charge is coulomb's (C)

I = Q/t Equation 1

Where I = current, Q = Charge, t = time.

Note: The current through a cross sectional area of the compressor is the amount of charge passing through the area per unit time.

Q = It Equation 2

Given: I = 121 A, t = 0.505 A.

Substitute into equation 2

Q = 121(0.505)

Q = 61.105 C.

Hence the charge passing through the cross sectional area of the circuit = 61.105 C
