Explanation:
Well 3 resistors
Resistance in parallel
Rt=1/r1+1/r2+1/r3 = 10.5263
Finding total current flow in circuit
It =V/Rt= 4.75A
Since Voltage remains the same across all resistors in an ideal parallel circuit. As stated by kirchofs voltage law. We can find the current through each resistor with a simple ohms law
Ir1=V/r1= 2.5A
Ir2=1.25A
Ir3=1A
Checking the calculations remain true by applying Kirchofs current law
It=Ir1+Ir2+Ir3 =4.75A
