Oh Thanks, by finding Ip I can find the power dissipated by the formula P = IV right?drvrm said:
Just to increase knowledge, where do we use the formula P = V^2/R ?Muhammad Danish said:
its v^2/RMuhammad Danish said:
A step-down transformer is a type of electrical transformer that has a higher number of windings on the primary coil than on the secondary coil. This allows it to decrease the voltage from the primary source to a lower voltage on the secondary side.
A step-down transformer works on the principle of electromagnetic induction. When an alternating current flows through the primary coil, it creates a changing magnetic field. This magnetic field then induces a voltage in the secondary coil, which is lower than the primary voltage due to the difference in the number of windings.
The main purpose of a step-down transformer is to reduce the voltage of an alternating current. This is useful in many different applications, such as in household appliances where a lower voltage is required for safety reasons, or in power distribution systems where high voltage transmission is more efficient.
The voltage ratio in a step-down transformer is determined by the ratio of the number of windings on the primary coil to the number of windings on the secondary coil. For example, if the primary coil has 100 windings and the secondary coil has 50 windings, the voltage will be halved on the secondary side.
Step-down transformers are commonly used in power adapters for electronic devices, such as laptops and cell phones, to convert the high voltage from a wall outlet to a lower voltage that can be safely used by the device. They are also used in power distribution systems to step down the high voltage from power plants to a lower voltage for household use. Additionally, they are used in various industrial and commercial applications to power equipment that requires lower voltages.
