Fixed voltage regulator: How to make a fixed voltage regulator? it’s an easy circuit diagram to make this circuit. we can use 100 voltage input and the output will be according to the ziner diode. here this circuit used 15 voltage ziner diode. so we can get 15 volts from …

How to make pure DC voltage: This is the circuit diagram to make pure DC voltage. we usually make DC voltage for our amplifier. but this is the best way to make pure DC. if we make voltage like this, there will be no bad noise from the amplifier. 1st …

auto cut-off battery charger: This is an auto-cut-off battery charger diagram for the 12-voltage battery. this circuit can protect the battery from overcharge. this circuit needs to be adjusted using the variable. at first, we have to fully charge the battery. after charging the battery we have to cut off …

How to make 5 voltage using tip41c: This is a 5-voltage circuit diagram for the Bluetooth card or charging 4.2-volt battery. or anywhere we want. we can use 7805 to make 5 volts. but 7805 can make half amperes. Sometimes we need more amperes. here used tip41c transistor. this transistor …

How to make ac to dc: this is the circuit diagram for making ac to dc voltage. this is a step-down transformer. always we have to use a step-down transformer to use the voltage. our primary voltage is ac 220. normally we need lower voltage. like 12 volts /24 volts …

How to make 12-voltage SMPS: This is the 12-voltage SMPS circuit diagram. this is an easy circuit. used here KLY MK-21C Universal Power as the MOSFET. first makes ac 220 to Dc voltage 350. then the dc voltage goes to the transformer using this KLY MK-21C Universal Power. the transformer …

How to make 5 voltage: This is a circuit diagram to make strong 5 voltage. normally we use 7805 to make 5 voltage for audio Bluetooth cards or others. but 7805 makes 500ma amperes. but sometimes we need 2 amperes. then we can use this circuit. this circuit can make …

Adjustable voltage regulator using lm317: This is an adjustable voltage regulator using lm317. we can control the voltage from 1 to 35 voltage. if we use 12 voltage then we can control from 1 to 12 voltage. if we use 24 voltage then we can control from 1 to 24 …

How to check positive and negative voltage: This is the circuit for checking the voltage. this circuit is for polarity checking for the negative and positive voltage. sometimes we have to check the voltage polarity wire when we use the same color wire for the voltage. normally it happens for …

How to make dc voltage: This is a circuit diagram for making voltage. this circuit is for dual volts. here used a full wave transformer. this transformer is ac 35-0-35 voltage. this ac voltage makes dc using 4 diodes and 2 capacitors. usually, this circuit needs an amplifier—positive- negative, and …
