It is known that R1 = 3 Ω and R2 = 6 Ω are connected in parallel, and the main circuit current is 1.5 A. what is the voltage of each resistor

Total resistance R = r1r2 / (RI + R2) = 3x6 / (3 + 6) = 2 Ω
The voltage of each resistor is u = IR = 1.5x2 = 3V

A resistor 5 Ω B resistor 10 Ω AB two resistors are connected in parallel and connected to the two ends of the 2V voltage source. What is the current in the main circuit? What is the total resistance at this time?

R total = RA / / RB = 5 / / 10 = 10 / 3 Ω
I dry = u / R total = 2 / (10 / 3) = 6 / 10 = 0.6A
The current in the trunk is 0.6A; the total resistance is 10 / 3 ohm
