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.
1. The total current within the circuit (IT) is equal to the sum of the separate currents in each direction (I1 + I2 + I3 + I4 + ....).
2. Electric current flowing into a point One is always equal to the current flowing from that point.
Characteristics of parallel circuits
1. The pressure drop across the element Or where all resistances of the circuit are equal because they are the same voltage at the same point
2. The current flowing in each branch of the circuit When taken together, it is equal to the current flowing through the entire circuit or the total circuit current.
3.Conductivity in each branch of the circuit When taken together will be equal
With the total conductivity of the circuit
4. Power generated at each element or resistance in each branch in the circuit, combined together, is equal to the total power and power of the circuit.
