A 10 ohm resistor is connected in series with a 15 ohm resistor. If this circuit is connected to a 9 volt battery, what will be the resultant current?
total R = 25 Ohms
i = V/R = 9/25 amps
To find the resulting current in the circuit, we need to apply Ohm's law, which states that current (I) is equal to the voltage (V) divided by the resistance (R).
1. First, we need to determine the total resistance in the circuit. In a series circuit, the total resistance is the sum of the individual resistances. So in this case, the total resistance (RT) is:
RT = 10 Ω + 15 Ω
RT = 25 Ω
2. Substitute the values into Ohm's law to find the current (I):
I = V / R
I = 9 V / 25 Ω
I = 0.36 A
Therefore, the resultant current in the circuit is 0.36 Amperes (A).
