Resistor problem

If a current of 15 A is flowing through the 15 ohm resistor. What is the voltage? Please see attached for diagram.

Series and Parallel Resistors

Hi. Actually, this is embarrassing, but my question is simply an algebra question. I know the equation and I know the answer, but I can't remember how to GET the answer. Can someone please walk me through this very simple algebra issue? Equivalent resistance in a circuit = 26 ohms R1 and R2 are parallel resistors; R1 = 55 oh

Resistors: Explanations and Calculations

(1) I have five circuits and want to run each one, one at a time, and then all five at the same time. My source is 12Vdc and 1500mA. The first circuit is 1.992 Mega ohms, the second is 3248 ohms, the third is 13.2k ohms, and the fourth is 0.247 Mega ohms and the fifth is .777k ohms. Now, the first four circuits use 5V and the


1. 45 A of current passes through a cross section of wire. How many charges pass through in 3 seconds? A. 9.375 x 10^19 B. 3.59 x 10^16 C. 2.16 x 10^17 D. 8.4 x 10^20 2. A 30 ohm resistor dissipates 500W of power. What current is running through the resistor? A. 15000 A

Maximum resistance

Suppose that you have a 460Ohm, a 850Ohm, and a 1.50kilo-Ohm resistor. What is the maximum resistance you can obtain by combining these?

Electrical Problem

A person has a 72 V battery along with 6, 9, and 18 ohm resistors. They are first wired in series, then is parallel. First, sketch each circuit. Then, find the current in each resistor as well as the voltage across each resistor for each resistor, for each circuit.

Resistor - Current of 5mA with Applied Voltage of 5V

An n-type Si resistor is to be designed so that it carries a current of 5mA with an applied voltage of 5V. T=300K. Mn*=.26M0. M0=9.11x10^31Kg. (a) If Nd=10^15/cm^3 and Na=0, design a resistor to meet the required specifications. (b) If Nd=3x10^16/cm^3 and Na=2.5x10^16/cm^3, redesign the resistor. What are the answers a

Voltage drop calculation

Referring to the attached circuit, determine the voltage drop (from top to bottom) across the 4 Ohm resistor.
