You connect 100 Ohm (R_1) and 20 Ohm(R_2) resistors in parallel to a 12-V DC voltage source as shown in Figure. Answer the following questions. What is the potential difference across the 100 Ohm resistor (R_1)? 10 V, 6.0 V, 12 V, 5.0 V What is the potential difference across the 20-Ohm resistor (R_2)? 10 V, 6.0 V, 12 V, 5.0 V What is the current I that goes through the 100-Ohm resistor (R_1)? 8.3 A, 1.7 A, 0.12 A, 0.60 A What is the current I- that goes through the 20-Ohm resistor (R_2)? 8.3 A, 1.7 A, 0.12,. 0.60 A Find the total (equivalent) resistance R of the circuit? 120 Ohm, 100 Ohm, 33Ohm, 17 Ohm
Explanation / Answer
A) c
B) c
C) 12/100 = 0.12 A
D) 12/20 = 0.6 A
E) 1/R = 1/ 20 + 1/ 100
R = 16.67 ohm
