A potential divider is a simple circuit that uses resisters(or thermistors / ldr's) to supply a variable potential difference they can be used as audio volume controls. Potential dividers divide up the voltage within a circuit, so that parts of a circuit only receive the voltage they require potential dividers form an important part of sensor circuits. Potential divider the potential divider is a line of resistors in series that are used to give different voltages in parts of an electronic circuit the voltages can either be set to fixed values or be adjustable. Igcse physics practical activity topic: potential divider objective: determine the resistance of a filament lamp by using potential divider circuit apparatus: 1) power supply.
So i am doing the ocr physics gcse course, and i have just learnt about potential dividers in electronic circuits i get that the first resistor steps down the voltage so a component with a lower. A potential divider is widely used in circuits it is based on the principle that the potential drop across a segment of a wire of uniform cross-section potential dividers are widely used in sensory circuits. Electric potential is the electric potential energy on a test charge divided by the charge of that test it's actually a bit too small for nuclear and particle physics, but the next largest si unit is the joule. The potential divider in the left-hand figure in the diagram below, three resistors are connected in the circuit divides the supply voltage into two separate voltage drops in the same ratio as the two.
In this page, you would learn about the potential divider circuit with fixed resistors, variable resistors and potentiometer we cannot simply use the potential divider formula to explain. A potential divider, or potentiometer, consists of a number of resistors, and a voltmeter the voltage read by the voltmeter is determined by the ratio of the resistances on either side of the point at which one end of the voltmeter is connected.
Using the potential divider formula: v = 6 x 333/(333+50) = 24v if you aren't sure about potential dividers, watch the video in the link.
