CONSTANT CURRENT CHARGING CIRCUIT

Generates a constant current (programmable from 0.1mA to 1.5mA in 0.1mA steps) to linearly charge a capacitor.
 
  • Chosen capacitor mounts in on-board sockets
  • Investigate Q-V relationship
  • Calculate charge from Q=It
  • Calculate capacitance from C=Q/V
  • Simple method of measuring capacitance, direct from definition
 
Supplied with components and worksheets.

Order Code: 04-003  Price: £15.90
