will the current flow through the circuit or not? give reason.
please urgent
Answers
Answer:
Current will not flow through the circuit.
Explanation:
As we know that circuit is a closed path of electric current. It is necessary to have a closed path for the current to flow. But it can be observed from the given figure that plug key is opened. Since key is opened current will not flow through the circuit. In order to flow of current by the circuit, the plug key should be closed.
Additional information:
~Resistance
Resistance means the opposition of flow of charge in a circuit. A device that creates such phenomenon is the resistor whose S.I. unit is ohm.
~Ammeter
Ammeter is a device connected in series connection with the conductor helps to get the reading of current flowing through the conductor.
It's resistance should be negligible so that current coil pàss through it.
~Voltmeter
Voltmeter is a device that is always connected in parallel connection with the conductor, its role is to measure the diffrence of potential between two terminals. It measures the voltage.
It's resistance should be very much high so that current could not flow through it.
