WebA battery is connected to a potentiometer. The potentiometer consists of a uniform resistance wire and a sliding contact P. The potential difference (p.d.) V between the sliding contact P and end Q of the wire is measured using a voltmeter. The sliding contact P is moved from end Q to end R of the wire. Sliding contact P is distance d from Q.

WebCurrent, potential difference, power and resistance Current, potential difference, power and resistance can be calculated to analyse circuits including potential dividers and … WebIf we rearrange this, we have: V 1 = V in x (R 1 / (R 1 + R 2 )) Since V out = V 1, we have: Vout = Vin x (R1/ (R1 + R2)) This is the potential divider equation. Sometimes you will see R 1 & …
WebA potential divider circuit consists of fixed resistors of resistance 2.0Ω and 4.0Ω connected in series with a 3.0Ω resistor fitted with a sliding contact.
