Question

Resistance of 8 ohm , 10 ohm and 5 ohm , are connected in series . calculate the equivalent resistance of the circuit
​

Answer 1

Answer:

The resistors with resistance 8 ohm 10 ohm and 5 ohm are connected in series.

Formula for net resistance in a series connection = R-series = R1 + R2 + .... + Rn.

Now, R1 = 8 ohm

R2 = 10 ohm

R3 = 5 ohm

So, R-series = 8 + 10 + 5

R(s) = 23 ohm

• The total net resistance in a series connection is the maximum value of resistance in a circuit.
• The total net resistance in a parallel connection is the minimum value of resistance in a circuit.
• The series connection and parallel connection are the two ways in which resistors can be connected.
• The voltmeter which is used to measure the the voltage in the circuit is connected parallel to the resistors.
• The ammeter which is used to measure the current in the circuit is connected in series.
• Formula for net resistance in a series connection = R-series = R1 + R2 + .... + Rn.
• Formula for net resistance in parallel connection = 1/R-parallel = 1/R1 + 1/R2 + .... + 1/Rn.

Answer 2

Answer:

8+10+5=23ohm.

equivalent resistance=23ohm.

Explanation:

when resistance connected in series then equivalent resistance is the sum of all resistances.
