How to determine equivalent resistance between terminals?

What kink of symmetry I can use to get the result? I think I have to redrew a circuit but how? The top array of 3 resistors is identical to the lower array of 3 resistors AND they connect to three ...

If i know a battery's internal resistance, how accurately can I predict its maximum current?

Yes, that's more-or-less correct. It's the greatest current that could flow with just the battery and a resistor. Of course you could connect batteries in parallel (series won't increase the current ...

How to best relate a case temperature measurement with the actual junction temperature?

Junction to case. The junction to ambient thermal resistance is the junction to case thermal resistance plus the case to ambient thermal resistance, without any heat sinking applied (or with some ...

Max voltage per pin when measuring differential voltage with MCP3422

You are interpreting it correctly. The voltage referenced to ground needs to be between -0.3V and 3.6V on each pin. You could achieve this by using a resistive 4:1 divider on each line, but this will ...

Equivalent resistance of a network

There's a few ways to go when limited by your calculator. Redraw the schematic and examine it for simplifications. Reduce the number of equations needed. Solve using the solver if the remaining ...

How to determine equivalent resistance between terminals?

This is an alternative solution using two Wye-Delta conversions. Due to part of the circuit being symmetric (excluding those two horizontal \$5 \space \mathrm{\Omega}\$ and \$2 \space \mathrm{\Omega}\$...
