Question

Calculate the equivalent resistance between the points A and B in the following circuit
A) 2Ω B) 3Ω C) 4Ω D) 5Ω

Answer 1

Upper 2 resistors are in series. Their equivalent resistance is
R = 6 Ω + 6 Ω = 12 Ω

Now it’s parell to below 6 Ω resistor
Equivalent resistance = 12 Ω × 6 Ω / (12 Ω + 6 Ω)
= 4 Ω

Equivalent resistance between A and B is 4 Ω

(C) is the correct option.

Answer 2

ANSWER :-

□ Equivalent Resistance between the points A and B = 4 ohm.

MORE INFORMATION:-

□ Resistance is the property that opposes the flow of charges.

□ It is represented by R.

Resistance = Potential difference / Current.

□ The SI unit of Resistance is ohm. (Greek letter omega).

□ The electrical resistance per unit length, area, or volume is known as resistivity. 

□ Resistance and Reactance combines sometimes vectorially to yield impedance.

□ Resistance contrasts with conductance.

□ If the resistance is doubled, the current is halved.

□ If the resistance is halved, the current is doubled.

□ It is a force that opposes the flow of electron in a direction.
