The term, 'negative current' simply refers to the sense or direction of a current compared with an assumed, standard, direction. For example, in the case of a battery, we normally assume that current leaves its positive terminal and enters its negative terminal (assuming conventional flow), and this is considered its 'positive direction'. However, if that battery were to be connected to a battery charger, the actual current would flow in the opposite sense to the assumed current direction and, so, it would be considered to be a 'negative' current.
So, the simple answer is, yes, we can measure a 'negative current' by using an ammeter. In the case of d.c., it may be necessary to reverse the connections to that ammeter to ensure that it reads upscale.

Should current be measured with the power off the circuit?
It will not be possible to measure current unless the circuit is powered and operating.
What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.
Which instrument do you use to measure the flow of current in a circuit?
To measure current you will need an ammeter.
Why was the capacitor discharging current negative?
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery. Current flowing out of an element, by convention, is defined as negative current, while current flowing into an element, such as a resistor, is defined as positive current. Thus a discharging capacitor will always have a negative current.
The flow of negative charges through matter is called?
A continuous flow of negative charges is called an electric current.
Should current be measured with the power off the circuit?
It will not be possible to measure current unless the circuit is powered and operating.
Is it possible to live in a world without negative integers?
No. Inventory and engineering work need negative numbers to measure. Also, how can we measure the temperature if it's freezing cold without negative numbers? Integers are needed for calculations and measurements in this world.
What determine the polarity of the voltage across a resistor?
A: Current flow only one way form positive to a less positive point. However it is possible to measure negative and positive voltage drop it the meter leads are reversed.
What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.
Can current be negative?
A negative current only signifies direction.
Is it possible to measure power factor for dc system?
noAnswer'Power factor' is a quantity associated with alternating-current systems, and does not apply to direct-current systems'.
Is it possible to have negative decimal numbers?
yes, it is possible to have a negative decimal.
The change from negative to positive and from positive to negative in an alternating current?
Is called AC voltage or current.
What is the significance of negative values of voltage and current?
What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
How do you measure negative pressure?
negative pressure is measured in negative inches of mercury
What is the direction of current due to flow of electrons if it is not conventional current?
Electron flow is from negative to positive. Conventional current flow is from positive to negative.
What is a measure of force with which negative charges flow called?
The force that causes negative charges to flow is the electromagnetic force. And we often apply the term voltageto the force that causes electron current to flow in what we normally think of as electricity.
