Transformers are electrical devices used to step up or step down voltage levels in power systems.
Transformers are used to increase (step up) or decrease (step down) voltage levels in electrical power systems.
Step up transformers are used to increase voltage for long distance transmission, while step down transformers are used to decrease voltage for distribution to consumers.
Transformers work on the principle of electr...
Ohm's law states that voltage is directly proportional to current when resistance is constant (V=IR).
Voltage (V) is equal to the product of current (I) and resistance (R)
It is used to calculate the relationship between voltage, current, and resistance in an electrical circuit
It helps in determining the amount of current flowing through a circuit for a given voltage and resistance
