Hint: When a conductive path is established to allow electric charge to move indefinitely, an electric circuit is produced. A current is the continuous flow of electric charge through the conductors of a circuit, and it is commonly referred to as "flow" in the same way that liquid flows through a hollow pipe. In an electrical circuit, resistance is a measure of the opposition to current flow. Current denoted by I and resistance denoted as R.Here, we are going to learn about the relationship between Current and Resistance.
Complete step by step answer:
Resistance and current are inversely proportional in the most basic sense. While Ohm's law describes the relationship more explicitly and includes voltage also, we will focus on current and resistance for the time being. Resistance is inversely proportional to current, which means that as resistance grows, current drops, and as resistance lowers maximum voltage.
A few such examples include:
The current halved when the resistance doubled.
When the resistance is increasing by a factor of six, the current is reduced by a factor of six.
The current doubled when the resistance cut in half.
Additional information:
A circuit's current flow is a mix of electron and hole flow.
The continuous and uniform flow of charge around the circuit is known as current. It is measured in Amperes or Amps and denoted by the letter of I.
Voltage is directly proportional to the current i.e., .
An alternating current's effective (RMS) value has the same average power loss as a direct current running through a resistive device.
The obstacle to the current flowing around a circuit is called resistance.
Low resistance indicates a conductor, while high resistance indicates an insulator.
Resistance is inversely proportional to the current i.e., .
Note:
Ohm's Law describes the relationship between current, voltage, and resistance. If the temperature is constant, the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the circuit resistance.
By Ohm’s law,
To increase the current flowing through a circuit, either the voltage or the resistance must increase.
