Question

Applying Kirchhoff’s Junction Rule, what happens to the power source and current when the parallel circuit has two branches, each with a resistor, R? In one to two sentences, answer the question and explain your reasoning.

Answer 1

The power source voltage remains the same in a  parallel circuit,

And we'll have equal current in both lines

Kirchhoff's junction rule

Generally, Kirchhoff's junction rule states that when there is current flow at any junction of a circuit, the total sum of this current rushing into the junction amount to the same amount of current out of the Node.

Therefore, when the parallel circuit has two branches

i=i1+12

Since we have an equal resistor therefore we'll have equal current in both lines i.e i1=i2

And Voltage remains the same in a  parallel circuit
