The AC voltage source supplies an rms voltage of 146 V at frequency f. The circuit has R = 110 Ω, XL = 210 Ω, and XC = 110 Ω. At the instant the voltage across the generator is at its maximum value, what is the magnitude of the current in the circuit?

1.03A

Explanation:

For computing the magnitude of the current in the circuit we need to do the following calculations

LCR circuit impedance

= 148.7Ω

Now the phase angle is

Now the rms current flowing in the circuit is

= 0.98 A

The current flowing in the circuit is

= 1.39 A

And, finally, the current across the generator is

= 1.03A

Hence, the magnitude of the circuit current is 1.03A

that the claims meet official rules.

don't misinterpret the claims

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
