Please tell which cab be utilized in place of it…Means to say 10pic of 1 ohm 1/2watt in parallel. and likewise clarify me if i used 2n3055 as a substitute of bc547 then what happen during this cricuit…Can u solve one query sir. If i attach two resistance in parallel in their wattage can be increased or not . Let feel i’ve got 1/2watt resistance then if i connect into parallel so matlab can change matlab matlab wattage or not… Means to increase or not. Can i used two variables resistor for controlling both voltage and current…. If i used then tell me where both were attached… In matlab diagramSorry sir 1ohm variable resistor is not accessible in my marketplace sir… Can i use 10k, 5K, 4. Silva, L. G. Reis, M. Freitas, L. B. Rodrigues, D. Hi swagatam, Actually i am in matlab center of your automatic charger with hysteresis feature. I just added engineering few changes . i will connect matlab circuit with this mail. plz check this out. If this circuit isn’t always ok then i can wait so that you can tomorrow . I forgot to ask one element.
