WebTime control for charging of common 9V rechargeable batteries ( NiCd and NiMH 9 V batteries.) The timer takes longer because these can only be charged at much lower current rate of 0.1C or 1/10C ( mAhr/10 = charging time in hours ) of their mAh capacity value. Usually between 30 mA to 100 mA depending on the 9V battery capacity in mAh. WebQuestion 1. A current of 2 A flows for 30 seconds through a lamp. How much charge has moved? Question 2. A current of 12 A flows for 20 minutes into an electric cooker. How much charge has the cooker used? Question 3. If 18400 C of charge flows through an air conditioning unit every hour, what current does it draw? Question 4.
