1) What are the current trends regarding electrical generation. Why?

2) Describe why people sometimes throw away perfectly good devices after they "check things out" and determine that the battery is good

• For this physics question, it wants me to find the unknown resistance, Rx. R1 has a resistance of 50, R2 has a resistance of 75, and Rx has a resistance of 100 ((they give us the unknown value but you have to find it using an equation and then you compare the actual value to what you got). I got the total resistance to be 23.08, but I don't know what to do after that. Please help me

• Please help with this question. I have to find Rx using the slope of the graph. R1 resistance is 50 ohm, R2 has a resistance of 100, and the Rx resistance is 100 ohm (they give us the unknown value but you have to find it using the slope and then you compare the actual value to what you got). The graph is Current 1 and then Current x Please help me i am so stuck.

The question specifically asks that I am not simply placing data values from a given row of your table in and then solving the circuit for Rx. You are to determine the mathematic expression for the slope of the line based on your knowledge of the Kirchhoff's and Ohm's laws.

I am finding the resistance for a parallel circuit and it wants me to find the formula for total resistance using Ohm's Law, V=IR (be specific with the correct subscripts - ie. V1 = I1R1 would represent the voltage across R1 precisely)

• ### Physics Question?

1) What is the current through the 24 ohm? The voltage?

2) Using kirchoff's voltage low and current law determine the voltage and current through the remaining 1 ohm resistor

Okay, so I know the equivalent resistance which is 10 ohms, total current leaving the battery which is 1.0A and the voltage across 3.0 ohm resistor which is 3.0 volts. The potential difference between the ends of the 8 ohm resistor is 6v and the current is .75A.

I need help with this question for physics 11

Explain how conventional current would be defined differently if early scientists understood that the current they were "playing with" really was
