If a bulb of 5ohms is connected across a 12V battery, what is the current flow through the bulb? The formula for this problem would be great, I can solve it from there.
I = E/R
2.4
To determine the current flow through the bulb, you can use Ohm's Law. Ohm's Law states that the current flowing through a conductor (such as a bulb) is directly proportional to the voltage across it and inversely proportional to the resistance. The formula for Ohm's Law is:
Current (I) = Voltage (V) / Resistance (R)
In this case, the voltage across the bulb is given as 12V and the resistance of the bulb is given as 5 ohms. Plugging these values into the formula, we have:
I = 12V / 5 ohms
Calculating this, the current flowing through the bulb is:
I = 2.4 Amps
Therefore, the current flowing through the bulb is 2.4 Amperes.
