Current is 5 amperes. voltage is 10 volts

AI Thread Summary
The discussion centers on calculating charge and time based on given electrical parameters: a current of 5 amperes and a voltage of 10 volts. The first calculation suggests that the charge for 30 joules of energy is 3 coulombs, derived from the formula Q = E/V. The second calculation indicates that the time required to supply 30 joules is 0.60 seconds, calculated using the formula t = Q/I. Participants express confusion about the context of the problem, questioning whether it is a homework question or lacks sufficient information for a complete solution. Clarification on the definitions of current, voltage, and energy is requested for better understanding.

current is 5 amperes. voltage is 10 volts.
1. what would be the charge if there is energy of 30 J?
2. what would be the time taken to supply the use of 30J?

For 1, is it 30J/ 10V = 3 coulombs
For 2, is it 3C/ 5 amperes = 0.60 seconds

Anyone can help?

While on one hadn this sounds like a homework problem (e.g. specifics stated), which we won't solve for you - only help - there is the other hand in which it doesn't sound like a homework problem (not enough info to solve the problem).

What are these things you're talking about?? Current is the rate at which charge flows. Voltage can be one of two things - it can be the difference in electric potential or it can be a measure of the emf in a circuit.

Energy is something different all together.

Please explain this question in more detail - perhaps by explaining what these charges and current and energy refers to.

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
