a 9 v battery produces a current of 18 amps. what is the resistance
E= IR
R = E/I = 9/18 = 0.5 ohns
To find the resistance, we can use Ohm's Law, which states that resistance (R) is equal to the voltage (V) divided by the current (I).
Given:
- Voltage (V) = 9V
- Current (I) = 18A
Using Ohm's Law:
Resistance (R) = Voltage (V) / Current (I)
Substituting the given values:
Resistance (R) = 9V / 18A
Calculating:
Resistance (R) = 0.5 Ω
Therefore, the resistance is 0.5 Ω.
To calculate the resistance, you can apply Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I). In this case, the voltage is 9 V and the current is 18 A.
So, you can use the equation: R = V / I
Plugging in the given values: R = 9 V / 18 A
Simplifying the equation, you find that the resistance is 0.5 Ohms.
