Solved Example of Parallel Circuits
This example shows how you can mathematical concepts to calculate current and other parameters in a parallel circuit.
Calculate the total current and power across a The voltage 2k ohm resistor in the given circuit.
Firstly we calculate the total resistance of the circuit to calculate the current .Let the total resistance be Req then 1/Req=1/R1+1/R2+1/R3
1/Req=1/10+1/2+1/1
Req=8/5 k ohms
Now on applying ohms law
V=I*Req
9=I*(8/5)
I=45/8 mA
Hence total current in the circuit is 5.625mA
Now we want to calculate power across 2k ohm resistor . Since voltage across each resistor is same we use the formula P=V2/R So Power across 2k= (9)2/2= 40.5 mW
Hence power across 2k resistor is 40.5mV
