In this circuit arrangement, with a measuring current source and a storage capacitor, to prevent interference due to leakage currents and to provide for the possibility of adding successive measuring current pulses, a second storage capacitor (16), which can be optionally connected, and a feedback line (17) from a second capacitor (16) via an operational amplifier (13) connected between the first capacitor (15) and second capacitor (16). In particular, the capacitance of the second storage capacitor (16) should be large compared with the capacitance of the first storage capacitor (15). The circuit according to the invention can be advantageously applied for adding flashes in flash exposure meters. <IMAGE>
