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

- 18. With low-voltage DC power supply, the resistance of electrical appliances is constantly changing between 2000 ~ 6000 Ω. How to make a circuit with stable output current of 1mA? It is planned to use a single 9V or 12V battery as the power supply. The resistance value of the electric appliance changes greatly, so it is necessary to make 1mA current continuously pass through the electric appliance. It is better to add a regulating device so that the current can be adjusted between 1mA and 5mA, but when it is not adjusted, the current should be stable at a certain value, and the smaller the fluctuation is, the better. Under the premise of ensuring the current stability, the simpler the circuit is, the better Can lm334z with resistor and adjustable potentiometer achieve the goal? Why? Please explain the principle of constant current output of the circuit. If it is not convenient to explain, please give tips, such as telling me what concepts and principles I should understand to make this circuit
