1. The problem statement, all variables
and given/known data
I3 + I1= I2
[/B]
Homework Equations
I3 + I1= I2
Note that the equation I_{1} + I_{3} = I_{2} would have also resulted from taking I_{1} to the left, I_{3} to the left and I_{2} to the right.chuvacjoe said:I 1 to the right, I 3 to the right, and i 2 to the left as assumed from my first equation I 1 +I 3=i 2
The currents at each resistor can be calculated using Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R). So, the formula for calculating current at a resistor is I = V/R.
To measure the currents at each resistor, you will need a multimeter. Set the multimeter to the current (Amps) setting and connect the probes to the resistor in series. The multimeter will display the current flowing through the resistor.
The currents at each resistor can be affected by the resistance of the resistor itself, the voltage applied across the circuit, and the presence of any other components in the circuit such as capacitors or inductors.
If there is no current at a resistor, it means that there is no voltage drop across that resistor. This could be due to a break in the circuit or if the resistor has a very high resistance value. In this case, no current will flow through the resistor.
In a series circuit, the current at each resistor is the same, as it is only one path for the current to flow. In a parallel circuit, the current is divided among the resistors based on their individual resistance values. This means that the current at each resistor will be different in a parallel circuit.
