A Simple Electric Circuit Consists Of A Constant Voltage Power Supply And A Variable Resistor

The schematic diagram of a simple electric circuit.

A simple electric circuit consists of a constant voltage power supply and a variable resistor.

Unlike dc source which is constant ac source has variable current and voltage at regular intervals of time. What effect does reducing the resistance have on the current in the circuit and on the power output of the power supply. If the resistance of the resistor is doubled the current through the resistor is. Ohm s law says i v r then increase the electrical resistance electrical current will decrease.

Whenever current increases voltage must decrease and whenever current decreases voltage must increase. For a given amount of power there s an inverse relationship between voltage and current. This is the third principle of series circuits. It is mandatory to know the basic components of an electrical circuit and its functionalities.

A simple electric circuit is a lane or path where the electrical current flows through it. For alternating current passing through the resistor the ratio of current and voltage depends upon the phase and frequency of the supply. An ammeter and a voltmeter are connected properly in the circuit to measure the current through and potential drop across the variable resistor. The purpose of a power supply is to provide power for an electronic circuit.

This simple fact unfortunately has an adverse effect on power supply circuits. A simple circuit consists of a variable resistor connected to a battery. As you increase the resistance the current flow. Generally for high power applications ac circuits are used.

This circuit can be designed with three components like a resistor a voltage source and a conducting path. A simple electrical circuit has a constant voltage power supply and a variable resistor as a circuit. The supply voltage in a series circuit is equal to the sum of the individual voltage drops. Notice the voltage drops across each resistor and how the sum of the voltage drops 1 5 5 2 5 is equal to the battery supply voltage.

If the resistance of the resistor is doubled the current through the resistor is. Simple ac circuit using resistance.
