Three resistors are connected in series, A of 100Ω, B of 500Ω, and C of unknown value. The combination is connected across a 140 V supply, and the voltage across resistor A is 10 V. Calculate (a) the voltage across resistors B and C, (b) the value of resistor C, and (c) total power.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
