Three Resistors Three Batteries The diagram below shows a circuit where; R1 = 3.0 Ω, R2 = 6.0 Ω, R3 = 8.0 Ω, V1 = 14.1 Volts, V2 = 3.6 Volts, and V3 = 6.0 Volts. What is the value of I1? In solving this problem, initially pick the current directions as shown. If the actual current turns out to be in the opposite direction, then your answer will be negative. If you get a negative number, enter it as negative. I have tried to solve this problem by writing out junction and loop equations and setting them equal, but I have only been able to solve that I1 = I1.

ANALYSIS As the potential across the resistor increased, the current through the resistor increased. If the change in current is proportional to the voltage, the data should be in a straight line and it should go through zero. In these two examples how close is the y-intercept to zero? Is there a proportional relationship between voltage and current? If so, write the equation for each run in the form potential = constantcurrent. (Use a numerical value for the constant.) Compare the constant in each of the above equations to the resistance of each resistor. Resistance, R, is defined using R = V/I where V is the potential across a resistor, and I is the current. R is measured in ohms (), where 1 = 1 V/A. The constant you determined in each equation should be similar to the resistance of each resistor. However, resistors are manufactured such that their actual value is within a tolerance. For most resistors used in this lab, the tolerance is 5% or 10%. Check with your instructor to…

The value for RX is unknown, but it is known that I4, the current that flows through resistor R4, is zero. picture attached Question If the value of the resistor R2 were doubled, how would the value of the resistor R3 have to change in order to keep the current through R4 equal to zero? 1. R3 would need to be increased 2. R3 would need to be decreased 3. R3 would not need to be changed 4. There is no change that could be made to R3 to keep the current through R4 equal to zero.
