Mobile phone

Abstract

The invention discloses a mobile phone, which comprises a mobile phone interface, a resistor, a voltage detection unit and a current calculation module, wherein the mobile phone interface comprises an input port and an output port; the resistor comprises a first end and a second end, the first end is connected with the input port, the second end is connected with the output port, and the output port is also connected with reference voltage; the voltage detection unit is connected with the first end to detect voltage at the first end; and the current calculation module calculates a value of current flowing though the resistor according to the detected voltage and resistance of the resistor. Due to the modes, the mobile phone has a current measuring function, and can be convenient for a user to take along to measure the current by means of portability of the mobile phone, the current can be measured without an ampere meter, and the mobile phone has the advantage that: the mobile phone is convenient and practical.

Description

a mobile phone technical field The invention relates to the field of electronic technology, in particular to a mobile phone. Background technique At present, the application of mobile phones in my country is quite popular, but ammeters are not as popular as mobile phones. People generally do not carry ammeters with them. Therefore, when encountering emergencies, such as sudden circuit failures in some electronic products, maintenance personnel need to use ammeters. When measuring the current of electronic products, maintenance personnel often only carry mobile phones for communication instead of ammeters, so they need to purchase additional ammeters, causing inconvenience to users and waste of money. Therefore, there is an urgent need to provide a mobile phone with a current measurement function to solve the above problems. Contents of the invention The technical problem mainly solved by the present invention is to provide a mobile phone with a current measurement func...
