Two Ways Of Decreasing The Current In A Circuit?
IS it this pentiometer and ampostat
or
this
Yep, lower the voltage or increase the resistance.
your Yep answer is correct.
You're partly correct! There are indeed two ways to decrease the current in a circuit: lower the voltage or increase the resistance.
Lowering the voltage: One way to decrease the current in a circuit is by lowering the voltage. This can be done by using a variable power supply or adjusting the voltage source. By reducing the voltage, the potential difference across the circuit decreases, resulting in a lower current flowing through it according to Ohm's Law (I = V/R).
Increasing the resistance: Another way to decrease the current is by increasing the resistance in the circuit. This can be done by adding resistors in series or parallel to the existing circuit. When resistance is increased, the current decreases based on Ohm's Law (I = V/R).
Both methods, lowering the voltage and increasing the resistance, result in a decreased current in the circuit. It's important to note that a potentiometer and ammeter are not specifically used to decrease current directly. A potentiometer is a variable resistor used to control voltage or divide a voltage source. An ammeter is used to measure electric current.
