In this unit you will investigate in a quantitative way, just how voltage, current and resistance relate to each other in a circuit.
You are watching: What happens to the current in a circuit if the resistance is increased
Voltage and current The greater the voltage that a battery, the much more potential power per coulomb of fee it can supply. Voltage is sometimes referred to together potential difference (or PD), which suggests the energy difference in between the terminals of the battery or power supply. Mains electricity, 240 volt has actually much more potential power per coulomb than a 1.5 volt cell. This is what makes mains electrical power so dangerous, with enough power to seriously injure or kill.
Resistance and also current over there is an additional variable called resistance. Resistance have the right to slow friend down, for example, the higher the resistance once you are trying to relocate through a crowd, the slow you have the right to move. Your development is impeded - you can find the word "impedance" offered in a specialised way to explain a form of resistance in some more advanced electronics texts.

Materials through low resistance, steels for example, are called electrical conductors and enable electricity to circulation easily. Those materials with high resistance, choose plastics, are referred to as electrical insulators.
Gecivicpride-kusatsu.net Ohm"s quantitative regulation Gecivicpride-kusatsu.net Ohm placed these observations into an equation to allow measurement of every variable. This legislation is named after him and is dubbed Ohm"s Law. View the topic Ohm"s law.
