How Resistors Work - Circuit Basics

WebThe job of a resistor is to limit the flow of current in a circuit and they do this by having a fixed resistive value. If we assume a resistor with a fixed resistive value of 100 Ohms, passes a current of 0.5 amperes (500mA), then the power dissipated by it will be, from Ohm’s Law, P = I 2 R = 25 watts, which is equivalent to 25 joules of work per second. WebNov 5, 2024 · The resistor is like a pipe that reduces pressure and limits flow because of its resistance. Conservation of energy has important consequences here. The voltage source supplies energy (causing an electric field and a current), and the resistor converts it to another form (such as thermal energy). arti fii amanillah ma'assalamah

WebThe main function of a resistor is to limit current flow. Ohm's law tells us that an increase in a resistors value will see a decrease in current. To reduce voltage , resistors are set up in a configuration known as ' voltage divider'. What is the current in the 5.0 ohm resistor? The current through the 5 - ohm resistor is 2.4 amperes. WebTo measure voltage, connect a resistor in series with the moving coil to limit current at the voltage being measured. This is referred to as the multiplier string. E = 0.001 A x (950 + 50) ohms E = 0.001 x 1000 = 1 volt for full-scale deflection.
