The formula for finding the terminal voltage Vab is Vab = V - IR, where V is the source voltage, I is the current flowing through the circuit, and R is the total resistance in the circuit.
In order to calculate the current, you can use Ohm's Law, which states that I = V/R, where V is the source voltage and R is the total resistance in the circuit.
The terminal voltage Vab is important because it represents the voltage that is present at the terminals of a circuit, which is what powers the circuit and allows it to function.
No, the terminal voltage Vab can never be larger than the source voltage. In fact, the terminal voltage Vab is always equal to or less than the source voltage, depending on the amount of resistance in the circuit.
The resistance in the circuit directly affects the terminal voltage Vab. As the resistance increases, the terminal voltage Vab decreases, and vice versa. This is because a higher resistance means there is more opposition to the current flow, which leads to a decrease in voltage.
