Test: Simple Parallel Circuits - Question 1

 From the given circuit, find the value of IR.

Detailed Solution for Test: Simple Parallel Circuits - Question 1

 In the given circuit, the voltage across the resistor is the same as the source voltage as they are connected in parallel. The current in the resistor is IR hence IR=V/R.

Test: Simple Parallel Circuits - Question 2

What is the relation between IR and V in the following circuit?

Detailed Solution for Test: Simple Parallel Circuits - Question 2

 In the following circuit IR and V are in phase because IR is the current in the resistor and the current in the resistor is always in phase with the voltage across it.

Test: Simple Parallel Circuits - Question 3

What is the expression for the current in the inductor from the following circuit?

Detailed Solution for Test: Simple Parallel Circuits - Question 3

In the given circuit, the voltage across the inductor is the same as the source voltage as they are connected in parallel. The current in the inductor is IL hence IL=V/XL.

Test: Simple Parallel Circuits - Question 4

 What is the phase relation between IL and V from the following circuit?​

Detailed Solution for Test: Simple Parallel Circuits - Question 4

 IL is the current across the inductor and we know that the current across the inductor always lags the voltage across it. Hence IL lags V.

Test: Simple Parallel Circuits - Question 5

Find the expression for the current I from the given circuit.

Detailed Solution for Test: Simple Parallel Circuits - Question 5

 I is the total current in the circuit. Since this is a parallel connection, the total current in the circuit is equal to the sum of the currents in each branch of the circuit. Hence I=IR+IL.

Test: Simple Parallel Circuits - Question 6

Find the total current if IL=2A and Ir=5A.

Detailed Solution for Test: Simple Parallel Circuits - Question 6

We know that I=IR+IL.
Substituting the values from the question, we get I=7A.

Test: Simple Parallel Circuits - Question 7

Find the value of IR if I=10A and IL=8A.​

Detailed Solution for Test: Simple Parallel Circuits - Question 7

We know that I=IR+IL.
Substituting the values from the question, we get IR=2A.

Test: Simple Parallel Circuits - Question 8

 Find the value of IL if I=10A and IR=6A.

Detailed Solution for Test: Simple Parallel Circuits - Question 8

We know that I=IR+IL.
Substituting the values from the question, we get IL=4A.

Test: Simple Parallel Circuits - Question 9

What is the expression for the current in the capacitor in the following circuit?​

Detailed Solution for Test: Simple Parallel Circuits - Question 9

In the given circuit, the voltage across the capacitor is the same as the source voltage as they are connected in parallel. The current in the capacitor is IC hence IC=V/XC.

Test: Simple Parallel Circuits - Question 10

What is the phase relation between IC and V from the following circuit?

Detailed Solution for Test: Simple Parallel Circuits - Question 10

 IC is the current across the capacitor and we know that the current across the capacitor always leads the voltage across it. Hence IC leads V.
