How to draw a circuit diagram involving voltmeter and ammeter?

Meep asked: The circuit has one parallel (two resistors) and two other resistors in a series. If we found the current in every resistor, do you show that on the circuit diagram? so basically my question is.. do you only put the A in one part of the diagram? or with each resistor? i’m just […]


Now I shall introduce my somple diode counter. To start off with, the MC145152-2 A-counter can have a count of 512, 1024, or 2048. This means that a 12.8MHz crystal, divided by 1024, will give you a reference frequency of 12.5kHz. You could alternatively use 6.4MHz divided by 512. Not many options there! You still […]
