Question 77Electricity & Electronics - QMED
70% to passWhat is the current flow through R1 of the circuit in figure "B" of the illustration with the switch closed if the resistance of R1 is 2 ohms, R2 is 3 ohms and R3 is 6 ohms and the battery voltage is 12 VDC? Illustration EL-0019
A2 amps
B4 amps
C6 amps
D12 amps
AI Explanation
The correct answer is C) 6 amps. To calculate the current through R1, we can use Ohm's law, which states that current (I) is equal to voltage (V) divided by resistance (R). In this case, the voltage is 12 VDC, and the resistance of R1 is 2 ohms. Plugging these values into the equation, we get: I = V/R = 12V / 2 ohms = 6 amps. The other answer choices are incorrect because: A) 2 amps is too low, as the calculation shows the current is 6 amps. B) 4 amps is too low, as the calculation shows the current is 6 amps. D) 12 amps is too high, as the calculation shows the current is 6 amps.
