Question

How does one calculate the entire resistance in parallel circuit?

Answer 1

Hint : Resistance may be a measure of the opposition to current flow in a circuit. Resistance is measured in ohms, symbolized by the Greek letter omega. Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the connection between voltage, current and resistance.

Complete Step By Step Answer:
The Effective Resistance of Resistors Connected in Parallel:
1. There are three important characteristics during a parallel circuit:
(a) The electric potential is the same across each resistor.
(b) The present that passes through each resistor is inversely proportional to the resistance of the resistor.
(c) The entire current within the circuit equals the sum of the currents passing through the resistors in its parallel branches.
When two or more resistances are connected between two common points in order that an equivalent electric potential is applied across each of them, they're said to be connected in parallel. When such a mixture of resistance is connected to a battery, all the resistances have an equivalent electric potential across their ends.
To calculate the entire overall resistance of the variety of resistors connected during this way you add up the individual resistances. This is often done using the subsequent formula: R total = $R_1 + R_2 +R_3$ then on.

Note :
To calculate the resistance of an electrical component, an ammeter is employed to live the present and a voltmeter to live the electric potential. The resistance can then be calculated using Ohm's law.
