RafaA transistor is a semiconductor device used to amplify or switch electronic signals, while a resistor is an electrical component that resists the flow of current in a circuit, thereby controlling the amount of current. Transistors are active components that can amplify signals, while resistors are passive components that mainly control the current and voltage levels in a circuit.

What is the phase difference between the current through the resistor and inductor in an AC circuit?
The phase difference between the current through the resistor and inductor in an AC circuit is 90 degrees.
How did the word transistor originate?
The word "transistor" is a blend of "transfer" and "resistor," reflecting its function of transferring electrical signals across a resistor. It was coined by John R. Pierce, an engineer at Bell Laboratories, where the first transistor was developed in 1947.
What is the voltage across the resistor at this instant in the circuit where Vab is measured?
The voltage across the resistor at the instant in the circuit where Vab is measured is equal to the potential difference between points A and B.
How to find the potential difference across a resistor in an electric circuit?
To find the potential difference across a resistor in an electric circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). So, you can calculate the potential difference by multiplying the current flowing through the resistor by the resistance value of the resistor.
What is the difference between a bipolar transistor and a field effect transistor?
A bipolar transistor uses both majority and minority charge carriers for conduction, while a field effect transistor primarily relies on majority charge carriers. Field effect transistors have a higher input impedance compared to bipolar transistors. Additionally, bipolar transistors are current-operated devices, while field effect transistors are voltage-operated devices.
