Magnetic Force on Wire 2: Verification Needed
1. Wire 1 is oriented along the y-axis and carries a current I1. A rectangular loop located to the right of the wire in the xy-plane carries a current I2. Find the magnetic force exerted by wire 1 on the top wire of length b in the loop labeled "Wire 2" in the figure.2. F = IL x B 3. Attached...- mathguy831

Finding current and potential difference within a circuit
So for part B) I found that the potential difference from c to f could be expressed using the equation: Vc - E2 + i2R2 = Vf Reworking the equation to get Vc - Vf on one side of the equation and after plugging in I found the potential difference to 54.4 Volts.- mathguy831

Finding current and potential difference within a circuit
So I reworked part a) trying to follow what you guys recommended. I applied Cramer's rule as I managed to find something similar in my notes after all and this is what I got. It ended up in milliamp like gneill said so I hope this is the right answer. Can anyone confirm this please? I am...- mathguy831

Finding current and potential difference within a circuit
1. For the circuit shown, (a) Find the current in each resistor (b) Find the potential difference between c and fHomework Equations :[/B] i2 + i1 = i3 i = V/R3. (a) So solving for each resistor using the loop rule this is what I got, (Resistor 3): E3 - IR3 = -E2 - E1 (Resistor 2): -E2 - IR2 =...- mathguy831

What is the relationship between electric potential and electric field?
So when plotting the graph correctly this time it still formed a straight line, but with a steeper slope. So from there would I find the slope using (y2 - y1)/(x2 - x1) and then work that into the equation for a line y = mx + b? (10 - 2)/(0.06 - 0.03) = 266.7 V/m Then solving for b in the...- mathguy831

What is the relationship between electric potential and electric field?
Okay, I graphed it wrong then I'll work on fixing that. But what about deriving an empirical equation. I'm still having trouble getting started on what to do.- mathguy831

What is the relationship between electric potential and electric field?
Q1: Use the graph (see attachment) to write the empirical equation V(r) for a charge cylindrical shell with appropriate constants, including units. Show all work. Q2: What is the interpretation of the horizontal axis intercept? Q3: What is the significance of the slope of the graph? I...- mathguy831
