1. How Will resistance change when the voltage increases in an electrical circuit if the current remains constant
A. It will decrease ****
B. It will stay the same
C. It will increase
D. It will decrease, then increase
I actually think its increase now
I don't agree with your answer. Why not use some numbers and see what happens. For example, E = 100, I = 50; R = ?.
Then E = 100 and I = 50; R = ?. The general rule is
E = IR so R = E/I. If I is constant than R = E*(1/k); therefore, if E goes up then R goes up. If E goes down then R goes down.
think really which one is it
R=v/I
=100/50
=2 ohms
To determine how resistance changes when voltage increases in an electrical circuit while keeping the current constant, we can refer to Ohm's Law, which states that voltage is directly proportional to current and resistance.
Ohm's Law can be expressed as V = I * R, where V is the voltage, I is the current, and R is the resistance.
If the current remains constant, we can rewrite Ohm's Law as R = V / I.
In this case, since the current (I) is constant, if the voltage (V) increases, the resistance (R) will also increase.
Therefore, the correct answer is C. It will increase.
