Yes, certainly - an operational amplifier circuit (see e.g. Wikipedia) will do this. For instance, a non-inverting amplifier circuit with a gain of 10 will give 1.0V output for 100mV input, 2.0V for 200mV, and so on (limited by the supply voltage of the amplifier). Physical sensors such as thermocouples or strain gauges often need DC amplification to make their outputs easier to measure.
When it's assembled into a circuit with other components and a power supply, atransistor can be used to amplify changes in voltage, but it can't amplify voltages.
A: Amplify DC a1 volt can be amplify to 10volts for example if need be
Like AC, DC can be at any voltage.
24volt dc

+ and - voltages not connected to earth
A bipolar junction transistor (BJT) can amplify DC signals, but it requires proper biasing to operate in the active region. By applying a DC input signal to the base, the BJT can control a larger DC current flowing from the collector to the emitter, effectively amplifying the input. However, the amplification is limited to small variations around the bias point, and the BJT cannot amplify a constant DC level without an input signal. Therefore, while BJTs can amplify DC, they are primarily used for AC signal amplification.
For measuring voltages, both Ac and Dc
AC amplifiers are used to amplify AC signals and use components that handle large voltage values. DC amplifiers are used to amplify DC signals which use small powered electronic devices.
