Judge the equivalent resistance when the following are ... - Toppr
Since 1 Ω and 106 Ω are connected in parallel . then the equivalent resistance R will be . 1 R = 1 1 + 1 10 6. R = 10 6 10 6 + 1 ~ 10 6 10 6. R = 1 Ω. Equivalent resistance is 1 Ω (b) 1 Ω and 103 Ω and 160 Ω are in parallel. 1 R = 1 1 + 1 10 3 + 1 10 6. 1 R = 10 6 + 10 3 + 1 10 6. 1 R = 1001001 1000000. R = 0.999 Ω. Therefore ...
