Draw a circuit diagram which depicts two resistor R1 and R2 connected in parallel with the source of ammeter voltmeter key and rheostat
Answers
Answer:
Components of the circuit:
1. Voltage Source (i.e. A battery):
It will maintain the potential difference along the circuit.
2. Rheostat:
It is a variable resistance. Using this property we can control or regulate the current in the circuit.
3. 2 resistors:
Resistance is the property of a conductor by the virtue of which current flow is opposed in the circuit. The resistors are connected in parallel combination.
4. Ammeter:
It is a modified Galvanometer used for measuring the current in the circuit. It is connected in series with the circuit
5. Voltmeter:
It is also a modified Galvanometer. It is used to measure the potential drop along the resistances. It is connected in parallel to the circuit.
6. Key:
It maintains the continuity of the circuit. It acts as a Switch.
Now refer to the attached photo to understand better .
Answer:
Diagram in attachment.
Explanation:
Voltage:
Voltages are a measure of the electric power available to cause the movement or flow of electrons. Thus, voltage by itself means no motion of electrons, but the ability to move electrons.
Ammeter:
It is a device used to find or measure the value of current flowing in any circuit. Ammeter is a very low resistance device and with its help, it is always placed in series in the circuit to measure the current.
Rheostat:
A rheostat is an electrical instrument used to vary resistance.
Key:
This protects the continuity, connectivity of the circuit and as this behaves as a switch.
Battery:
This is a important sources which balance, maintains the potential difference between the circuit.

Purpose of adding resistance in parallel order is to reduce the effective resistance of the dielectric coil because we have read that the effective resistance in parallel order is 1 / R = 1 / R1 + 1 / R2.
