Question

nichrome wire, 10w bulb and torch bulb are connected in an electric circuit one by one separately ( one at a time).is the current flowing through the circuit same or different? give reasons

Answer 1

all this electrical components are connected separately in a circuit therefore current flowing through each component will be different.
this combination is a parallel combination and current flowing through each component is depends upon its resistance.

Answer 2

The current flowing through the circuit for each of the components will be different. It depends on the voltage source present in the circuit and the resistance of the component as current = voltage divided by resistance.

Assuming the voltage source to be same in each case and different resistances of the components, the value of current in the circuit for each case will be different.
