Question 10
The current running through a circuit is 10 amps from a 5 V battery. Calculate the resistance.
a
2 Ohms
b
Not enough information
c
50 Ohms
d
0.5 Ohms
To calculate the resistance in a circuit, you can use Ohm's Law which states that the resistance (R) is equal to the voltage across the circuit (V) divided by the current passing through it (I). In this case, the voltage is given as 5 Volts, and the current is given as 10 Amps.
Using Ohm's Law, the equation would be:
R = V / I
Plugging in the values, we get:
R = 5 V / 10 A
Simplifying, we find:
R = 0.5 Ohms
So, the correct answer is option d: 0.5 Ohms.
