A series R-C circuit consumes 160 W at a power factor of 0.8 leading when connected to a 100 V, 50 Hz supply. The value of resistance R is:

For an R-L series circuit connected to an AC source of 13 V, if the voltage across the 2.5 Ω resistor is 5 V, then the current flowing through the circuit is _______ and the voltage across the inductor is _______.

A resistor of 50 Ω is connected in parallel with a capacitor whose capacitive reactance is 20 Ω. The parallel circuit is connected across a 100 V supply. The total current drawn from the supply in complex rectangular form (I = IR + jIC) is:
