The Voltage, V(in volts), across a circuit is given by Ohm's law: V=IR
Where I is the current (in amps) flowing through the circuit and R is
the resistance (in Ohms). If we place two circuits, with resistance R1andR2, in parallel, then their combined Resistance, R, is given by

The current and voltage in a circuit is given by:
The instantaneous current and voltage in an a.c. circuit is given byI=4sinωtE=150cos[ωt+π3] respectively then the phase difference between voltage and current in the circuit is given by
Phase angle between voltage and current in RLC circuit is given by
