Questions & Step-by-Step Solutions
Which type of transformer is used for impedance matching?
Step 1: Understand what a transformer is. A transformer is a device that changes the voltage of electricity.
Step 2: Learn about impedance. Impedance is a measure of how much a circuit resists the flow of electricity.
Step 3: Know why impedance matching is important. It helps to ensure that maximum power is transferred between different parts of a circuit.
Step 4: Identify the type of transformer used for impedance matching. An isolation transformer is commonly used for this purpose.
Step 5: Understand the role of an isolation transformer. It not only matches impedance but also isolates different parts of a circuit to prevent interference.
