To calculate the total resistance of a circuit, you need to add the individual resistances of all the components. In this case, the total resistance would be R1 + R2 + R3, which equals 50 Ω.
The formula for calculating current in a circuit is I = V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms. In this case, with a total resistance of 50 Ω and a voltage of 10 volts, the current would be 10/50 = 0.2 amperes.
To determine the current through each resistor, you can use Ohm's law (I = V/R) or Kirchhoff's circuit laws. In this circuit, since all the resistors are in parallel, the current through each resistor would be the same, which is 0.2 amperes.
Yes, you can use a multimeter to measure the current in this circuit. Set the multimeter to measure amperes and connect it in series with one of the resistors. The reading on the multimeter should be 0.2 amperes, which is the total current in the circuit.
The resistance of a component affects the current in a circuit because the higher the resistance, the lower the current. In this circuit, R3 has the highest resistance and therefore has the lowest amount of current flowing through it compared to R1 and R2.
