In a circuit containing a pure resistor connected to an AC source,

Step-by-step solution

In a purely resistive AC circuit, the alternating voltage is given by V = V₀ ( t) . According to Ohm's law, the current through the resistor is I = V R = V₀ R ( t) = I₀ ( t) . Comparing the expressions for voltage and current, the phase angle for both is t . Thus, the phase difference between them is zero. Therefore, voltage and current are in the same phase with each other. Answer: Voltage and current are in same phase with each other
