Question

How many amps are there in 220 volts?

Answer 1

Hint:Before solving this question let’s have some idea about voltage and current. Voltage is nothing but the emf and current is the flow of charges in a circuit.

Complete step by step solution:
The amps and volts are the different units used to measure the current and voltage in a network or a circuit. Voltage can be defined as the potential difference between the two points in a network or it is also defined as the work done in bringing a charge from one point to another. The S.I. unit of voltage is given as volts denoted by V.

Current will flow in the circuit when there is a difference in electric potentials between any two points in a medium of conduction. The S.I. unit of current is ampere or amp denoted by A. Electrical equipment that is in our home is operated at 220 volts but current drawn by them is at a different rate. For example, if you consider a heater and fan.

These two operate at 220 volts but here the current which is drawn from the both is different, that is, heater draws more current than refrigerator. Therefore, we can say that the power consumed by the electrical appliances helps us to find the value of current if voltage is provided.

Hence, the number of amps present in 220 volts totally depends on the power consumed by the appliances.

Note:Volt and ampere are different quantities. We can connect this by a law known as Ohm’s law. This is a basic law in electronics. This law is used to calculate the resistance and voltage in the given circuit. Thereby, by calculating the resistance and voltages one can easily find the current and power. There are three basic quantities used in Ohm's law : volts (V), amps (I) and Ohms (R). These three quantities are interrelated. Changing one affects the other two quantities and their relationship is as follows: \[V = I \times R\], \[I = \dfrac{V}{R}\] and \[R = \dfrac{V}{I}\]
