What is a pure resistive circuit?
Think about what elements are present.
State Ohm's Law.
Relate it to its components.
In a pure resistive circuit, the current and voltage are:
Think about what 'pure resistive' means.
The power factor in a pure resistive circuit is:
Consider how power is utilized.
Given a circuit with a resistance of 80 Ohms and a peak voltage of 240 Volts, determine the current and the power factor. Explain your steps.
Refer to Ohm's Law for current.
If an alternating current circuit has a sinusoidal wave function for voltage given as V(t) = 200 sin(120πt), calculate the peak current when connected to a 50 Ohm resistor.
Extract the peak voltage from the sine function.
