Use a plug in clamp if your multimeter isnt rated high enough for the circuit. How to increase the current of the power supply duration.

Evertech 18 Channel Port 12v Dc 10 Amp Amper Ul Listed With Ptc Fuse Distributed Power Supply Box For Cctv Dvr Security System And Camera Or Cameras
How to increase amperage of 12vdc. 2512v dc to 220v ac project inverter. 3012 volts 64 amps dc motor generator 750 watts. If the circuits resistance remains unchanged the amperage in a circuit can be increased by increasing the voltage. How to make a 1 amp to 50 amps current boost inverter circuit diy. Hitoday am going to teach you how to make an extreme current booster circuitwe all have seen the high voltage booster circuits where little voltage supply is transformed into a high voltage low current supplyin fact i have made certain hig. Just plug the leads into the multimeter and attach the other end to the circuit the way you would attach the multimeter clamps.
By keeping the voltage exactly the same but lowering the resistance you will increase the amperage of the circuit. Video on how to build an ac to dc converter that outputs variable voltage 12 16 dc volts up to 130 amps. This video how to make a simple output dc current increase using 2n3055 transistor for variable voltage regulators the component is using 1 2n3055 transistor 2 lm7812 voltage regulator 3. The plug in clamp accessory can extend the range. Rewiring a circuit increasing the voltage and decreasing the resistance in a circuit nearly always involves rewiring the entire circuit unitrewiring a circuit requires turning off all power to the circuit breaker.
