Parallel circuit
    For the voltage in a parallel circuit across each resistor Is equal to the voltage of the power supply. The voltage across each resistance which is equal to
VR1 = VR2 = VR3 = VR4 = VS = 9V
The current in a parallel circuit
    The current within a parallel circuit has multiple values. This is because there is more than one direction of current flow, so the calculation of current is done using Kerchhoff, s Current Law.
