Energy equals voltage multiplied by present.

The elemental equation that governs the connection between energy, voltage, and present is: Energy (watts) = Voltage (volts) x Present (amps)

This equation, sometimes called Ohm’s Legislation, is the cornerstone {of electrical} calculations. It implies that the quantity of energy consumed or generated by a circuit is instantly proportional to the voltage throughout the circuit and the present flowing via it.

As an example, take into account a light-weight bulb with an influence score of 100 watts related to a 120-volt energy supply. Utilizing Ohm’s Legislation, we are able to decide the present flowing via the bulb:

Present = Energy / Voltage

Present = 100 watts / 120 volts

Present = 0.83 amps

Due to this fact, on this circuit, 0.83 amps of present flows via the sunshine bulb, ensuing within the consumption of 100 watts of energy.

For instance, suppose you might have a 60-watt mild bulb related to a 120-volt energy supply. To calculate the present flowing via the bulb, you’ll divide the ability (60 watts) by the voltage (120 volts):

Present = Energy / Voltage

Present = 60 watts / 120 volts

Present = 0.5 amps

Due to this fact, on this instance, 0.5 amps of present flows via the 60-watt mild bulb.

Voltage stays fixed in a collection circuit.

In a collection circuit, the voltage stays fixed all through the circuit. Which means the voltage throughout every part within the circuit is similar. It’s because the present flows via every part in succession, and the voltage drop throughout every part provides as much as the full voltage of the circuit.

For instance, take into account a collection circuit with a battery, a resistor, and a light-weight bulb.
