Explanation:
Current and Charge
The current is a measure of the charge through a conductor over time. If the charge is a function of time it can be computed as
If the charge flow is constant in time, then the current is computed as
Using the values provided in the problem, we have
Answer: 1/R = 1/r1 + 1/r2 + 1/r3
Explanation:
Just did the test myself. Hope this helps!
Answer:
The power dissipated in either one of the parallel resistors is 2 V
Explanation:
Given;
two parallel resistors, R₁ and R₂ = 2 ohms
The total resistance of the Two resistors of 2 ohms connected in parallel is;
when connected to another resistor of 1 ohm in series, the total resistance becomes;
Rt = R₁ + R₂
Rt = 1 + 1 = 2 ohms
Current in the circuit, I = voltage / total resistance
= 2 /2 = 1 A
the overall circuit has been resolved to series connection, and current flow in series circuit is constant.
Power = I²R
Thus, power dissipated in either one of the parallel 2 ohms resistors is;
Power = I²R = (1)² x 2 = 2 V
