How higher load (high R) draws more current when the nature of resistance is to reduce/restrict the current?
Consider a voltage in a circuit(say 100 V) in a closed circuit, and a resistor 10 ohm and a Load of 20 ohm connected across it.
when you turn on the switch, current through them is almost 100/30 (3.33~...

Voltage drop reason not understood
I am using a 12V 5A adaptor to power a 12V pump and a 12V solenoid valve. The solenoid valve is supposed to pull 600mA, the pump is supposed to pull 0.6-1A. Hence to play safe the 12V 5A adaptor. ...

MIC2251 5V Booster - voltage drops when load is connected
I have a step-up circuit that boosts 2.8-4.2V on the input to 5V.
The problem is when I connect any load to it at the output, it loses around 1V and I have no idea why.
The Step-up IC is MIC2251:

In a transformer, how do you determine where the induced EMFs (E) and voltages (V) are placed in a vector diagram?
I will be citing pictures from Electrical Technology by Theraja.
So there are different cases with regards to the transformer depending on what losses and loads are considered. Each of them have ...
