You may compute how much current is going through the conductor by reading the amount of current produced by the coil

These are Carbon Film Resistor with a value of 160 ohm 1/4W and tolerance of ±5%

SPDT(Single Pole Double Throw) relay is used as a switch for high current AC/DC appliances which need to be controlled from a microcontroller or sensor output

74LS74 Two D Flip-Flop IC (7474 IC) DIP-14 Package Qudcopter It is an 8-Bit CMOS74LS Series ICs are High Speed Logic gates, ideally a little faster than 74HC series but more power consumption is required. They are implemented with a Low Power Schottky diode technology to achieve high switching speed. 74LS74 is one of the 74LS series IC. 74LS74 ICs contain two independent positive edge triggered D flip flops with complementary outputs. These ICs can set or reset the outputs by using preset (PRE) or clear (CLR) input at a low
