What does a resistor show?

The resistor is a vital component found in almost every imaginable electronic circuit. It shapes the electrical signal as it passes through based on the voltage and current. A bad resistor could ultimately lead to other components of a circuit failing, or the complete shut down of a circuit altogether.

What does a resistor accomplish?

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

What happens to current after a resistor?

The current after a resistor is the exact same as it was before the resistor. If you now add a resistor in series into this circuit – the current of the circuit will be smaller. So yes, the resistor does reduce the current. (But the current flowing into the resistor is still the same as the current flowing out.)

What does a resistor affect?

So following the law a resistor must affect both voltage and current however the reality is that it only changes one size.

What is the value of resistor?

A resistor is a device that opposes the flow of electrical current. The bigger the value of a resistor the more it opposes the current flow. The value of a resistor is given in ohms and is often referred to as its ‘resistance’.

Do resistors stop current?

In short: Resistors limit the flow of electrons, reducing current. Voltage comes about by the potential energy difference across the resistor.

Does resistor decrease current?

The resistor reduces the current, just like the narrow pipe reduces the flow rate. The current before and after the resistor is the same, just like the flow rate before and after the narrow pipe is the same. It reduces the current compared to a different circuit where the resistor is replaced with an ideal wire.

How do resistors affect power?

The unit of power is the Watt (W). When the voltage is increased, the current, I, increases and the power dissipated by the resistor, R, increases. When the value of the resistor is increased, I decreases and the power dissipated by the resistor, R, decreases.
