Question

how to determine equivalent resistance

Answer 1

Answer:

Explanation:

The equivalent resistance of a 4-Ω and 12-Ω resistor placed in parallel can be determined using the usual formula for equivalent resistance of parallel branches: 1 / Req = 1 / R1 + 1 / R2 + 1 / R3 ... Now the Ohm's law equation (ΔV = I • R) can be used to determine the total current in the circuit.

Answer 2

The equivalent resistance of a set of resistors in a series connection is equal to the algebraic sum of the individual resistances.

(a) Three resistors connected in series to a voltage source.

(b) The original circuit is reduced to an equivalent resistance and a voltage source.

hopefully its helped u dear :)
