电路 基尔霍夫定律 KVL and KCL Kirchhoff's Laws and Circuit Analysis (EC 2) •Circuit analysis: solving for I and V at each element •Linear circuits: involve resistors, capacitors, inductors •Initial analysis uses only resistors •Power sources, constant voltage and current •Solved ...
Taking the version of the circuit (from post #4) where the central resistors have been reduced to a single value (594.958 Ω): Write the two KVL loop equations and the KCL equation for the junction at point B. You can write them symbolically for now; forget plugging in numbers for now...

That's a bit less than you'd predict from the single load result: 34/4 = 8.5 Ohms for four of them in parallel, which goes to show that the circuits are drawing more power to compensate for the drop in supply voltage. Your circuit will look something like this: With the load ...
Circuit Measurements Voltage (V)Current (A)Power (W) R1 R2 R3 Simulation powered by PLECS using WebSIM® patented technology Working principle According to Kirchoff’s Voltage Law (KVL), the sum of all voltages around a loop is equal to zero. When going around the loop, intuitively...
Generally Rvoltmeter is chosen to be much greater than any resistance in the circuit, and voltmeters are put in parallel with circuit elements to measure the voltage across them. What one is measuring with...
