1. (TCO 1) In a circuit, 3.5 V is across a resistor, resulting in a current of 6

Question

1. (TCO 1) In a circuit, 3.5 V is across a resistor, resulting in a current of 6.25 mA. What is the resistor value?

Question 2.2. (TCO 2) A 5-V source produces 12 mA of current, how much power is being drawn from the power supply?

Question 3.3. (TCO 2) If R1 is 680 ohms, 1/8 watt resistor, calculate the power dissipated by R1, and evaluate if it is operating within it's safe limits. There is 10 V on one end of R1, and -2 V on the other end.

1. (TCO 1) In a circuit, 3.5 V is across a resistor, resulting in a current of 6.25 mA. What is the resistor value?

Explanation / Answer

1. r=V/I= 3.5/(6.25*10^-3) =560ohms

2. P=V*I= 5*12*10^-3= 60KW

7. Req= r1*r2/(r1+r2) = 1.33kohms

please include circuit diagrams for the rest of the problems
