Question

Drawing of a circuit diagram that contains a series battery with four cells, two light bulbs connected in parallel, a voltmeter across each light bulb and an ammeter that measures the main current

Answer 1

An electrical circuit is a closed path that includes all the components connected to complete the flow of current.

Explanation:

The circuit below consists of:

• A battery as a source of direct current which supplies energy in the circuit for current to flow. Direct current provides uni-directional current. Here it has two cells. Here four cells are connected in series for the battery.
• Two bulbs A and B connected in parallel connection. Each bulb has been parallelly attached with a voltmeter.
• A voltmeter measures the voltage across the component that it is connected with. It is always connected in parallel with the components.
• Main circuit has an ammeter in series with the battery and connection of bulb.
• An ammeter measures the current flowing in the circuit. It is always connected in series.
