1. A parallel circuit has
a) parallel branches only.

Explanation: In a parallel circuit, the components are connected in such a way that there are multiple paths for the electric current to flow. These paths are called parallel branches.

2. A parallel circuit is used in order
a) to have the same value of current in all the elements.

Explanation: In a parallel circuit, each component has its own separate path for the flow of electric current. This means that the current can be different in each branch, but the same current flows through each component within that branch.

3. In a parallel circuit, a trouble in one branch
a) results in no current in that branch only.

Explanation: In a parallel circuit, if there is a problem or issue in one branch, it does not affect the other branches. Each branch operates independently, so if there is a trouble in one branch, it only affects that particular branch.

4. No current in a parallel circuit
a) results from a trouble in one branch.

Explanation: If there is a problem or trouble in one branch of a parallel circuit, it can lead to the absence of current in that particular branch. However, the other branches will still have current flowing through them.

5. The sum of IR voltage drops
c) is more than the value of voltage in the circuit.

Explanation: In a parallel circuit, the total voltage drop across each component (IR voltage drop) is equal to the total voltage applied to the circuit. This means that the sum of all the individual voltage drops across the components will be equal to the total voltage of the circuit.
